What measures do precision parts processing require for their lifespan? The lifespan requirement is to ensure that the parts maintain normal operation during the expected working period without being scrapped. This requirement is mainly for parts that are subjected to wear or corrosion during operation under variable stress.
The main factors that affect the fatigue limit of part materials in precision parts processing are stress concentration, size, surface quality, and environmental conditions. Therefore, the main measures to improve the lifespan of parts are:;
1. Properly involving precision component processing structures to reduce stress concentration;
2. Using processed or surface strengthened treatment to improve the quality of the working surface of the parts;
3. Reasonable selection of friction pair matching materials, lubricants, and lubrication methods to improve the wear resistance of parts;
4. Select corrosion-resistant materials to manufacture parts that work in corrosive media;
5. Utilize heat treatment to improve the mechanical properties of component materials, or use processes such as rolling and shot peening to generate favorable residual stresses on the surface of the component.
